I just stumbled on this guy a few days ago and can't believe I was out of the loop for such a long time. He's funny as hell and kinda reminds me of the Chinese guy from The Hangover.
The problem with race based humor, is that you tend to be either so bland and cliche it's not offensive at all and you just don't care because you've just heard it all before. Or you go wayyyyyyy too far and it's just racist.
